# RF-CONCRETE Deflect | Input

### Product Feature

000130 29 April 2015

The deformation analysis is activated in the settings for analytical serviceability limit state design of the RF-CONCRETE Surfaces add-on module where you can also specify the settings for long-term effects (creep and shrinkage) and for tension stiffening between concrete cracks. The creep coefficient and shrinkage strain are calculated using the specified input parameters or defined individually.

You can specify the deformation limit value individually for each surface or for an entire surface group. The allowable limit value is defined by the maximum deformation. In addition, you should determine if the design applies to a deformed or non-deformed system.
